ABSTRACT

Abstract: The problem of providing rice to feed the population of Indonesia nationally until now is still a problem for which need to be addressed.One alternative to be able to help overcome this problem is to develop the cultivation of upland rice in immature rubber plantations.This research aims to obtain an adaptive upland rice variety grown in immature rubber plantation with an appropriate soil tillage method and the optimal dose of organic matter to obtain high rice productivity.This research using split - split plot experimental design with 3 factors and 3 replications.The first factor is the soil tillage method consists of 3 methods (1.Soil cleaned with a hoe, then planted. 2.Soil tillage method 1 time with a hoe, flattened, then planted. 3.Soil tillage method 2 times with a hoe, flattened, then planted). The second factor is an organic material consists of treatment doses : 0 tons/ha, 5 tons/ha, 10 tons/ha dan 15 tons/ha. The third factor is the upland rice varieties (Si Kembiri and Situ Patenggang).The results showed that Situ Patenggang variety provide highly significant effect on the increase in the number of tillers and number of panicles per hill of plants compared to Si Kembiri variety. Organic material at dose of 5 tons/ha giving the highest significant effect to increase in the number of panicles per hill of upland rice crop. Combination of soil tillage method 2 times and Situ Patenggang variety giving the best significantly effect on increasing : the number of productive grain per panicle, grain weight per hill of upland rice plant and grain production per experiment plot. Combination of organic material at dose 5 tons/ha with Situ Patenggang variety giving best effect to the increased number of productive grain per panicle, grain weight per hill of upland rice plant, and grain production per experiment plot.
